When “CSI: Crime Scene Investigation” hit TV screens back in 2000, it changed the face of cop shows forever. No longer were detectives supposed to rely on their intuition to solve cases, but instead, the evidence became key.

The “NCIS” finale turned out to be a shocker. Tony (Michael Weatherly), Ziva (Cote de Pablo) and McGee (Sean Murray) resigned, laying their badges down on Vance’s desk, and four months later, Gibbs (Mark Harmon) is on a mission that finds him pointing his sniper rifle at Senior FBI Agent T.C. Fornell (Joe Spano). We are left with the question: Is Fornell the target? Or is it someone he is guarding?

In last week’s penultimate “NCIS” episode of the season, guest star Colin Hanks accused Gibbs (Mark Harmon) of manipulating evidence and obstructing justice — and to do so, he brought not just two but four men with him to place Gibbs under arrest.

With the CBS Upfronts just days away, the future of ‘NCIS: Red’ will soon be determined. If it does get a pickup, it would be the third spinoff in the series, which began with “JAG,” moved to “NCIS,” and was followed by “NCIS: Los Angeles.”
